　　Industrial Gas Turbine blades are the key component of gas turbines.For the large size blade casting, liquid metal cooling (LMC) is used in the directional solidification process to get higher temperature gradient.However, Columnar-to-Equiaxed Transition (CET) and freckle and other casting defects easily occur during the directional solidification of turbine blade castings.To reduce the developing cycle and cost, numerical simulation technology can be used to predict the casting defects and optimize the directional solidification process by liquid metal cooling.
